About a year ago, a band mate of mine was involved in the probate and liquidation on a deceased neighbor’s property. There were some tube goodies so he gathered them and sold them to me for $50 before they got on the auction. In the haul, there were two amps (both 6v6 push-pull power amps), a reverb unit, and this power supply built by the decedent. It’s pretty cool from the front... Dangerous from the bottom... ...and even more dangerous from the back. The lugs on the right side put out from zero to 500 VDC depending on how you adjust the 2 chicken head knobs. Might come in useful someday!
